E2E TD-SCDMA:
It’s a Qualcomm project. TD-SCDMA is a TDD variant of UMTS – CDMA, mainly used in countries like China. E2E (end to end) project includes scripting and validating testcases for this technology which checks the peer messages between UE and Network. Testcases are scripted using TTCN-2 language and peer messages are written as per specifications and Abstract Syntax Notation files. These testcases are then validated on Network Simulator (Anritsu and Starpoint) and Qualcomm reference mobile phones. The validation can be manual or automated on the system simulator. There is a adaptation layer which sits in between TTCN and system simulator.
I was awarded with ‘Outstanding Performer’ twice in consecutive quarters.

Responsibilities:
Scripting testcases for different modules like multiple PDP, fast dormancy, OCNS, state transitions, multi RAB reconfigurations, Handovers etc in TTCN
Developing the core framework and coding the Adaptation Layer lying between TTCN and SS in C language.
Developing test scripts for different chipsets such as DSDS, DSDA, SGLTE etc.
Debugging logs in case of testcase failures.
Validation of tescases on Starpoint and Anritsu (SS).
Unit testing, Stability testing, regression testing.
